The main aim of this study was to adapt the Mobile Attachment Questionnaire (MAQ) to Turkish culture. It was also aimed to investigate whether mobile phone attachment (MPA) exists in Turkish university students and whether it has the main characteristics of interpersonal attachment. This study also aimed to investigate the MPA's relationship with nomophobia, smartphone addiction and materialism, and to examine the predictive power of them on MPA. The study group consisted of a total of 242 university students. Exploratory and confirmatory factor analyses were conducted to determine the structural validity of the MAQ-TR. The goodness of fit indices met the model fit requirements for the four-factor 13-item MAQ-TR. Reliability analyses results provided high internal consistency coefficients. Correlation analyses results showed that individuals highly attached to their phones experienced more severe symptoms of nomophobia and smartphone addiction and materialists were more likely to accept their phones as attachment object. Regression analysis showed that nomophobia, smartphone addiction and materialism were significant predictors of MPA. Given that MPA is an understudied concept, this study provides a starting point for future researches on problematic and non-problematic phone use.
